Chain food is chain food, the quality is going to stay consistent.
This particular Olive Garden is always packed, I personally would suggest making a reservation during the weekends.
On an experience I had here, my waiter spilled water all over me, by accident.
He was clearly flustered, which is probably why I got no apology, from the waiter, nor do I think the manager even knew.
For me the tables are too close together and I feel cluttered when I'm at this Olive Garden, but overall this is not a terrible place-- its alright.
